To all whom it may concern:

Be it known that I, J OHN C. COTTIE, a citizen of the United States, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Belt-Couplings, of which the following is a specification.

This invention relates to a belt coupling, with the object in view of providing a simple, durable and effective coupling for securing the ends of a belt together, leaving the face of the-belt toward the pulleypr wheel over which it passes free from any metallic projection or surface.

A further object is to provide a coupling which may be stamped from sheet metal and which will distribute the strain throughout substantially the entire width of the belt.

A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 is an outer or face view of the coupling as it appears when in use, Fig. 2 is a transverse section in the plane of the line A-A of Fig. 1, Fig. 3 is a face view showing the pars detached, Fig. 4 is a transverse section of the same in the plane of the line B-B of Fig. 3, Fig. 5 is a view in detail of the blank from which the female l section of the cou ling is formed, and Fig. 6 is a view in detail of the blank from which the male section of the coupling is formed.

The ends of the belt to be coupled are represented by 1 and 2 and their relation when coupled and in use with respect to the pulley is illustrated in Figs. 1 and 2, the pulley being denoted by 3.

The blank from which the female section of the coupling is formed is denoted by 4. It may be'stamped from a sheet of metal,

for example sheet steel, and is provided along one .of its edges with a series of tongues 5 spaced apart and provided at their outer ends with reduced extensions 6. At its opposite edge, the blank 4 is provided with a series of sharp prongs 7 spaced apart and preferably located opposite the tongues 5.

The male section of the coupling is denoted by 8. It is provided along one edge with a series of T-shaped tongues 9, the heads of said tongues beingdenoted by 10. The spacing of the tongues 1,9 on the male sections oorresponds'to the spacing of the tongues 5 on the female section but the inner bending of. the ton tongues 9 are so arranged that they will center with the spaces between the tongues 5 on the section 4. The opposite edge of the section 8 is provided with a series of sharpened prongs 11 spaced. apart and preferably located transversely opposite the spaces between two consecutive tongues 9.

The section 4 is completed for use by bending each of the tongues 5 into the form of an eye as clearly shown in Figs. 2'and 4, the body of the tongue 5 being first bent inwardly away from the plane of the body of the section 4 and then upwardly and over until the end of the reduced portion 6 of the tongue extends within the body of the eye passing close to the section 4 in proximity to the base of the tongue 5.

In bending the tongues 5 to form eyes, it is intended that the edge of the body of the section 4' at the base of the tongues 5 shall be bent inwardly. thereby forming a continuous smooth bearing 12 for receiving the outer corner of-the end 1 of the belt.

When the tongues 5 are bent to form the eyes, the reduced extensions 6 on said tongues form between them and the edge of the body 4 of the section, elongated sockets 13 for the reception of the heads 10 of the T-shaped tongues 9 on the male section, the stems of the T-shaped tongues 9 passing between the tongues 5 when their T-heads are received in the sockets 13, the free ends of the reduced portions 6 serving to space the heads 10 one from another with the stems of the tongues 9' centered in the spaces between the tongues 5.

The sections are secured to the belt by extending their prongs 7 and 11 transversely through the belt and then bending the extreme ends of the prongs outwardly into recesses or depressions 14, 15, on the inner face of the belt, the extreme ends of said prongs being forced into the body of the belt to such an extent as to leave no projecting metal on the inner face of the belt.

As these interlocking tongues and fastening prongs may be formed at frequent intervals along the opposite edges of the respective sections of the coupling and as the coupling may be extended to approximately the width of the belt, the strains are well distributed throughout the Width while the p cs5 through the edge of the. body of t e female section brings the strain when the parts are assembled close to the exterior surface 01 the belt. Furthermore, the structure of the interlocking sections of the'coupling. is such that they may be formed and marketed in long strips and cut by the user into lengths exactly suited for the' particular width of belt to which. they are to be applied. The structure has the further advantage of requiring no riveting in order to secure the sections of the belt.

What I claim is:

1. A belt couplingcomprising interlocking sections, the one section being provided,

with a series of tongues along one edge hav= ing their extremities reduced the said tongues being bent into the form of eyes and the reduced ends-forming the end walls .of elongated socketsjand the other section beingflprovided along its 'dge with aseries of T-shaped tongues, the'heads of which are adapted to enter said elongated sockets, the opposite edges of said sections being providedzwithholding prongs for securing the coupling to a belt. f

2. The combination with the ends of a belt, of coupling sections, one of the coupling sections being provided with a series of tongues bent to form. eyes, the said coupling section having its edge from which the section being ada ted to receive the corner of one end of the elt, the other couplin section being provided with a series of shaped tongues arranged to seat in the eyes aforesaid, and both coupling sections being provided vwith pointed prongs arranged to hook into the b of the belt.

3.-A-belt coupllng comprising interlock ings tions, the one section being rovided with series of'tongues having r uced extensions bent over to form eyes, the ends of said reduced extensions extending within the body of the eye, and the other section being provided with T-sha ed tongues, the heads of which areadap to rest in said eyes with their stems between the tongues of the opposite section and their heads separated and centered by the said reduced extensions.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this eleventh day of February, 1908.
